    ESI not applicable


    Do not vaccinate stallions and horses in training.

    Side Effects

    In some animals, the injection of vaccine can cause a painful swelling which appears within 1 to 2 days and can persist for up to 2 weeks. For this reason injection into the rump is advised. Slight lameness may occur for a day or so in horses which react severely to the vaccine but this will not affect feeding or general well-being. Mildly affected animals may favour the leg on the vaccinated side.

    NOTE: If the vaccine is injected in the neck, the horse may have difficulty with feeding, particularly off the ground, for a few days.


    Vaccination is not recommended within 4 weeks of expected birth.
